We’ve got awesome
news to share:

The Big Bud 16V 747 is getting new “shoes!”

In June 2020 the original 8 ft. tall construction tires will be replaced with Goodyear LSW 1400/30R46 tires. Titan International, Inc. contacted Williams Brothers and offered these Goodyear Farm Tire assemblies with Titan Low Sidewall (LSW) Technology. The Williams Brothers had to provide new rims to fit.

WATCH this website for pictures and videos of the tire conversion which will be happening very soon.

Then we’ll own The World’s Largest Farm Tractor with the World’s Largest Ag Tires!
